Seoul was bathed in golden light, as if someone had sprinkled stardust over the city. The metropolis breathed in rhythm; the wind howled softly between towering skyscrapers, carrying with it the laughter of youth and the distant murmur of bustling crowds.
But today, the entire city pulsed to a single beat.
Far away, on Jindo Island
The BTS concert was in full swing.
Roaring screams of excitement rose like tidal waves, loud enough to be heard miles away. The stage was a breathtaking portal to another world, lit by dazzling lasers and massive holographic projections. Tens of thousands of light sticks swayed in unison, painting the night sky with a galaxy of artificial stars. The air trembled with anticipation and raw energy, every heartbeat syncing with the music's pounding rhythm.
Yet, not everyone was part of this dream.
Not far from Seoul's city center, inside the Korea Hunters Association's Control Department, life moved at a much slower, colder pace.
Here, towering walls of high-tech screens flickered with endless streams of data. Massive digital maps tracked real-time dungeon energy signatures from every corner of the peninsula. The work was simple—but crucial: detect newly manifested dungeons, monitor fluctuations in energy levels, and protect the public from potential disasters.
As noon approached, one of the department's younger analysts, Soyoung, leaned lazily against her desk, poking at her kimchi with chopsticks. Beside her sat her ever-cheerful, slightly gossipy friend, Mina.
"Ugh…" Soyoung sighed, resting her chin on her palm. "Girls… maybe we should've taken the day off and gone to the concert. Seriously, everyone is talking about BTS right now. Even the boss was humming their song this morning!"
Mina raised an eyebrow, smirking. "Tell me about it. But the tickets sold out instantly. Still…" She leaned closer, lowering her voice conspiratorially. "They're doing another concert in Daegu soon. We're going to that one. Deal?"
From across the table, Jisoo from the technical analysis team chimed in between bites of her now-cold tteokbokki.
"Jindo Island's pretty far anyway. Even if we had tickets, we'd never make it after work. Let's just stick with Daegu."
The three of them laughed, for a brief, fleeting moment forgetting about the burdens of their job. The world, for that short while, felt safe.
But that peace wasn't going to last.
Lunch ended, and everyone returned to their desks. Soyoung scanned the endless streams of energy readings as part of her daily routine. Lines of green stretched across the monitor, pulsing steadily everything perfectly normal.
Until she noticed a small red icon blinking in the corner of her screen.
Her brow furrowed.
"Hmm… Jindo Island… why is there no data feed?" she muttered under her breath.
She called out to Jisoo at the next desk:
"Jisoo, can you check this for me? I'm not getting any energy readings from Jindo Island. Is it a sensor malfunction, or did we lose the connection?"
Jisoo pulled out her earbuds, rolled over in her chair, and started typing rapidly.
"Hold on. Give me a second. I'll figure it out."
The two spent several minutes combing through system diagnostics. Jisoo eventually left to gather additional information, while Soyoung sat staring at the screen, absentmindedly scrolling through social media on her phone. Her friends' stories from the concert filled her feed, making her sigh with longing.
And then the door slammed open.
Jisoo burst in, her face pale, breath ragged, and forehead glistening with sweat.
"Soyoung!" she gasped. "Open the main map. Now!"
Confused, Soyoung obeyed. Her fingers flew across the keyboard, bringing up the map interface.
What she saw next froze the blood in her veins.
From Jindo Island, the energy readings…
They weren't just off the charts
They broke the charts.
The system struggled to even process the calculations, the numbers flickering wildly before finally displaying a single, terrifying line:
"Energy level equivalent to the combined total of 120 countries' dungeons."
Soyoung's hands trembled violently. Her throat tightened; words refused to come out.
"T-this… this is impossible…"
Jisoo stood frozen beside her, wide-eyed and pale, unable to move.Suddenly, sirens blared across the entire Control Department. Red emergency lights washed over the walls, alarms echoing through the corridors.
"Emergency alert! Code: RED.
All top-ranked hunters, report immediately!"
At the Hunters Association headquarters, the President convened an emergency council. Sitting at the head of the table, his expression was carved from stone, his knuckles white as he gripped the edge of the desk.
"Have you reached Omer Jin-Hoo yet?" His voice was sharp, cutting through the tension.
His aide lowered his head. "I'm sorry, sir… there's no response. We can't locate Hunter Jin-Hoo anywhere. We fear he may have disappeared… just like the Chinese hunter, Xu Liangchen."
The President's face darkened. His fist slammed against the table, the echo silencing the room.
"This… is unacceptable." He exhaled sharply, composing himself, then spoke with icy authority:
"Jindo Island is beyond anything we've ever faced. Find Omer Jin-Hoo, no matter what it takes."
Then, his tone shifted, his gaze sweeping across the gathered officers:
"Until he's found… deploy our strongest hunters. Mobilize the military. From this moment forward, Jindo Island is no longer just Korea's problem"
His voice lowered, heavy with grim finality:
"it's humanity's problem."
The Korea Hunters Association's emergency mobilization alarm blared through the control center, reverberating off every wall as sirens howled and massive holographic screens flashed crimson warnings. Red lights pulsed along every corridor while staff members sprinted in all directions, tablets and data consoles clutched tightly in their hands as they scrambled to coordinate the unfolding chaos.And yet… no one truly understood the magnitude of what they were facing.
SSS and SS-ranked hunters the strongest warriors Korea had to offer were summoned one by one to the central command. The operations hub, usually a place of cold precision, now felt like a sacred war temple, gathering the nation's mightiest to face an unseen calamity.
From Seoul, a fleet of specialized military helicopters tore through the sky, heading straight for Jindo Island.
The winds howled like a beast on the hunt, rattling the steel frames of the aircraft as thunderclouds churned ominously above. Inside the lead helicopter, Song-Kang, a seasoned SS-ranked hunter, gripped the cockpit's overhead handles and turned to address his squad.
"Relax, everyone," he said, his voice steady but sharp. "I'm here. We'll neutralize this threat before it spirals out of control."
From the back of the cabin, Kyung-ho let out a dry laugh, his expression half amusement, half warning.
"You? Don't make me laugh. If humanity's last hope rests on you, Korea's screwed."
A ripple of nervous chuckles spread through the squad, briefly cutting through the tension. But the storm outside reminded them relentlessly of the reality awaiting them—each passing second, the energy waves from Jindo Island grew stronger, heavier, almost alive.
Inside the cabin, every hunter had fallen into their own rhythm.
Some meticulously checked their equipment, others monitored live energy readings scrolling across their wrist consoles, while a few sat in silence, eyes closed, steadying their breathing before the storm.
Suddenly, Won-bin a brash, confident SS-ranked hunter leaned forward, cracking open a bag of roasted seeds and tossing a few into his mouth.
"You just watch," he declared loudly, his voice cutting through the drone of the rotors. "After this mission, I'm going to be promoted to Z-Rank. The government will build statues in my honor!"
Song-Kang shot him a sideways glance, smirking faintly.
"Maybe… if you put down those seeds and actually prepared for once."
A third hunter, sitting across from them, spoke up in a grave tone, his voice weighted with memory.
"Jokes aside… this isn't like anything we've dealt with before. It could be national-level… maybe even worse—like the dungeons that erupted in Tokyo and London."
A silence settled over the squad as he continued:
"Remember the last time? Two national-level hunters died on the field. We only survived because Omer Jin-Hoo and Xu Liangchen were there to save us."
At the mention of those names, the cabin fell into a heavy, uneasy quiet. Neither of those hunters was here now.
Outside, as they neared Jindo Island, the sky had transformed into a maelstrom of chaos. Towering storm clouds swallowed the horizon, bolts of lightning tore through the darkness like cracks in the heavens, and the wind battered the helicopters mercilessly.
Song-Kang checked the readings flashing on his control panel, his face tightening as he shouted over the roar of the storm:
"Stick to the plan, but stay sharp! This energy… it's unlike anything we've ever faced before."
Rain hammered against the cockpit windows, blurring the faint glow of distant city lights and casting everything in a gray, foreboding haze.
Amid the rhythmic pounding of rain and the roar of engines, one of the hunters sat silently at the far end of the cabin, his expression unreadable beneath the dim cabin lights.
A faint smile touched his lips as he whispered, almost too softly to hear:
"Hyung-nim… I'm proud of you."
At that moment, Hikari stepped a little outside the concert area to make a phone call; he wanted to check on his family. For the young hunter, this was a brief moment to calm himself and hear the voices of his loved ones.
Through the phone's speaker, his little sister's voice came through, slightly annoyed:
"Hey, why didn't you call, Hikari? I didn't even know about the concert!"
Hikari took a short breath, his voice calm yet firm:
"You're too young. This concert isn't for you. But don't worry, we'll go to the one in Daegu together."
His sister grumbled before abruptly hanging up. Hikari slipped his phone back into his pocket. Just then, a notification popped up on his screen from The Korea Times 코리아 타임즈
The headline made his heart skip a beat:
"Jindo Island in Danger. Hunters Association issues a red alert. Do not leave safe zones. Special Hunter Squads and the military have been mobilized to ensure the safety of those on Jindo Island."
Hikari opened the news article, his expression shifting instantly to shock. For a moment, it felt as though his heart had stopped.
"This is ridiculous… must be something the haters cooked up. A fake panic just to interrupt the concert…" he muttered to himself.
But then… something changed.
His knees weakened, and an overwhelming heaviness washed over his entire body. A faint ripple appeared in the air before his eyes, followed by a dark, oppressive aura that slowly engulfed the surroundings.
Hikari held his breath, scanning the area. People around him remained oblivious — but he could feel it. This wasn't normal. This was an energy wave… and it was anything but harmless.
He bit his lip and quickly pulled out his armored equipment, strapping it tightly around his body. His fingers didn't tremble, but his heart was pounding like a war drum.
"Who's there?!" he shouted, his voice carrying a mixture of fear and unyielding resolve.
As Hikari focused, he realized something terrifying this wasn't an ordinary dungeon surge. It was something immense, uncontrollable, and conscious.
His vision blurred at the edges, yet his mind remained crystal clear. A warning echoed deep within his consciousness:
"Prepare yourself… this will be the greatest catastrophe you've ever witnessed."
Hikari clenched his weapon, his grip tightening around the cold steel. The armored plates locked into place over his shoulders as the energy vibrations resonated faintly through his hands.
For the young hunter, this wasn't just danger.
It was a call to battle.
War was inevitable
